Final Notice
MAINTAINING RELIABLE ELECTRICITY SUPPLY TO PORT LINCOLN
Port Lincoln is situated on the southern tip of Eyre Peninsula, in the western region of South Australia. It is a major town on Eyre Peninsula and has a population of about 14,000. Electricity supply is provided by a radial 132 kV transmission line that connects Whyalla, in the north, to Port Lincoln, about 260km to the south. As a consequence of changes to ElectraNet’s supply obligations to the Port Lincoln connection point, planning studies have been undertaken to evaluate potential network and non-network options to address increased supply reliability requirements.
ElectraNet has identified appropriate augmentation and prepared a final report for the purposes of clause 5.6.6(c) of the National Electricity Rules in relation to a proposal to establish new large transmission network assets. The final report contains the results of planning investigations and economic assessment of feasible supply options that will address the increased level of reliability now required of supply to Port Lincoln, and recommends the contracting by ElectraNet of local generation support be adopted in order to satisfy the requirements of the ETC in relation to the Port Lincoln connection point.
